Application filed June 19, 1919. Serial No. 305,287.

Be it known that I, Jnssn A. B. SMITH, a citizen of the United States, residing in Stamford in the county of Fairfield and State of Uonnecticut, have invented certain new and .useful \Improvements in Typewriting-Machines, of which the following is a specification.

The present invention relates to book- 5 keeping devices, and is herein disclosed as comprising the carriage of an Underwood Such machines are frequently used for making entries on individual cards or memorandum sheets, and copies of such entries are often kept upon proof or record sheets, there usually being a single entry upon each memorandum sheet made at a time while the proof or record'sheets are retained in the machine and'all entries made thereon i sequence until the sheet is full.

According to the present invention, a simple device may be utilized for retaining the proof or record sheet in its adjusted position while a memorandum sheet or card 1s being inserted. This device may take the form of achute whichis adapted to receive the memorandum sheet and to bear against the surface of the proof sheet when the latter is passed around the platen, thereby retaining that sheet in place While. the usual feed-rolls are cast off. To enable the roof sheet to be withdrawn, the chute may he swung to a position clear of the platen,

thus relieving all pressure upon the proof' which presses a rounded key 22, connected sheet. I I

Other features and advantages will-hereinafter appear. In the accompanying drawings," Figure 1 is. a perspective view ofv a Underwood bookkeeping machine carriage,

- showing the present invention as applied thereto.-

1g. 7 is a perspective view diagrammatically showing the relationship of entries upon the. memorandum sheet recordsheet.

lFlg. 8 is a diagrammatic perspective view of the memorandum sheet as bent when around the platen.

The platen 1 is journaled by its axle 2 in the end plates 3 and 4 of the shift-frame wh ch forms part of the carriage 5 and in which 1t is adapted to be rotated by the usual line-space wheel 6 at the actuation of the usual handle 7. To insert the proof or record sheet 8, it is joined at the leading end,

by means. of clips 9, to a carbon sheet 10,

of the width of a memorandum sheet 11 and proof or pass forwardly and upwardly past thefront feed-roll 15 to the printing point at the type-guide 16'. Before reaching the print-.

mg-line, the leading edge 17 may engage paper-fingers 18 which extend, down almost tothe feed-rolls 15,,and Which are formed, as ,lower extensions o-f brackets 19 slidable upon -a transverse rod 20. To hold the fingers-18 yieldingly and slidingly in place, the brackets 19 each support a spring 21,

to the brackets into the spline 23 of therod 20. The fingers 18 are adapted to overlie the margins of the: proof sheet 8, and inelude directing plates 24 which extend down -9 near the platen and serve to guide the'advancing or leading edge 17 upwardly over .the rod 20. Fi 2 is a sectional side .view of the same,

Toinsert the memorandum sheet 11,:a

chute 25 is adapted to. normally rest its toes 26 with somepressureupon the surface of the proof sheet 8 as it lies upon the platen. The chute by this pressure holds the proof sheet 8 against slidingv on the platen, thus permitting the feed-rolls 14 and 15 to be cast off by actuating the usual casting-off handle 27. Then the typist lifts' the extension 28 of the bottom of the carbon sheet-10 which is long enough to always lie at a COIIVGIIlQIIt'POHIt upon the papertable 12 to be lifted when the printing line is upon the proof sheet. The typist then inserts behind it the memorandum sheet 11,

sliding the latter down over the paper-table 12 and over the feed-rolls 14 and 15 and up 'onto the top of the chute between the springy margins which are formed as turned-up edges 29 thereof. Then the typist may actuate the handle 27 to cast on the feed-rolls, thus clamping both sheets against theplaten. The memorandum sheet 18 then ready to be written upon.

If the item is the last item shown upon thesheet shown, the typist, in pursuing the usual course, first copies out the previously shown balance, which will be the one shown and deposits-columns 32 and 33 of the amount in the register above mentioned memorandum sheet. In entering the-amount in the deposits-column, the typistadds that Next the typist sets the machine to write in the balance-column 34 and copies therein the balance now shown in the register, namely, $2125.25, subtracting it out. Then the typist prints the usual star to prove the accuracy of the copying.

Usually only one entry at a time is made in a memorandum sheet, so the next step is to remove the memorandum sheet from the machine by first releasing the feed-rolls and then removing the sheet from the machine. In order to prevent the ribbon 35 and its vibrator from being entangled or caught by the memorandum sheet 11, there is provided a wire guide having offset feet adapted to fit in openings 38 in the baseof the type-guide and having wings 39 at each side of the U-top 40 which joinsthe two legs 37 said wings being flared outwardly and being stifi' enough to deflectthe memorandum sheet 11 when in position. As herein illustrated, the memorandum sheet isin the form of a card of considerable stiffness, y and it advantageously fits soclosely between the resilientspringy sides 29 of the chute Y 25 that it is'retained in position even if at the very top of the front feed-roll 15;.

' If the chute 25 is made of light and resilient enough metal, the edges or sides 29 will be springy enough to serve the purpose if they are simply bent up from the body of the chute and incline slightly outwardly: In

order to enable the chute 25 to be swung clear of the platen, to facilitate the insertion wherever set.

of the proof Sheet 8 and its carbon 10, a

finger-piece 41 may be pushedrearwardly, thus turning a shaft 42, to which it is fast, so that the chute 25, which is, so to speak, journaled on the shaft by ears 43, will be lifted from the platen." The shaft 42 turns so st'itHy in the brackets 44, in which it is mounted upon the ends 3 and 4, that it stays \Vhen the finger-piece is moved backwardly, the toe 26 of the chute stands clear of the platen, as shown in Fig. 2, and the proof sheet may be easily inserted. When the proof sheet has been inserted and properly centered, the chute 25 is moved back against the platen by pulling ,the finger-piece 41 forward.

In order to hold the chute 25 against the platen with some resilience, there isprovided a kerf 45 in the shaft 42, in which rests a rounded key46, which is pressed into the kerf 45 by a spring or springs 46 between the ears 43. The key 46 yields enough to give considerable spring to the chute 25 as it rides upon the platen, thus giving the requisite pressure without hindering the turning of the platen. In order to prevent theproof sheet 8 from catching its leading edge in the rod or shaft 42, there is provided beneath the chute 25 a deflector plate 48 for" caniming downwardly the leading edge of the proof sheet 8, said plate extending from near the toe 26 of'the chute rearwardly under the shaft 42, thus enabling the typist to be assured that the proof sheet 8.

consciously actuating the line-space lever 7, and then remove the card, thus leaving the proof sheet 8 in position for the next entry.

In order to give added resistance to accidental turning of the shaft 42, it may be frictionally held by a spring 49, supported against it by a small bracket 50 fast to one of the brackets 44.

Variations maybe resor-ted to within the scope of the invention, and portions of the improvements may be used without others. Having thus described my invention, I claim 1.
